Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
The inventor of the present disclosure finds that, in the existing passive wavelength division technology, a management means is lacking for an optical module equipped in a DU/AAU, which results in a passive wavelength division system having weak sensing capability for a fault of an optical fiber link, and is difficult to operate, maintain and manage the optical module, and when a system fault occurs, fault location is mainly performed manually. In order to better meet the 5G forwarding requirement, the capability of managing and controlling optical modules in the BBU/DU and the RRU/AAU needs to be provided. In the prior art, there is also a scheme for managing the optical module. For example, china mobile proposes an Open-WDM scheme, including an AAU color light module, an AAU side passive wavelength division multiplexer, and a DU side active WDM device, to form a unified management and control forwarding network. The DU-side active WDM equipment can manage the near-end color light module via the local II2 bus. However, the existing solution for managing the optical module mainly manages the near-end optical module on the DU side, and lacks a management means for the far-end optical module on the AAU side. Therefore, it is necessary to remotely monitor and control the remote optical module through the DU side optical module.
In view of this, as a first aspect of the present disclosure, a remote monitoring method for an optical module is provided, which is applied to a near-end optical module, and as shown in fig. 1, the remote monitoring method includes:
in step S110, a monitoring instruction is generated according to a predetermined data frame format;
in step S120, the monitoring instruction is sent to the remote optical module through a downlink optical signal, where the monitoring instruction is used to instruct the remote optical module to execute a corresponding monitoring service.
It should be noted that, in the 5G network, the near-end optical module is an optical module on the DU side, and the far-end optical module is an optical module on the AAU side; in the 4G network, the near-end optical module is an optical module on the BBU side, and the far-end optical module is an optical module on the RRU side. Of course, the remote monitoring method for the optical module provided by the present disclosure is not limited to a 5G or 4G network, and may also be applied to any other network system with a forwarding architecture, and the present disclosure does not make any special limitation thereto.
It should be further noted that, according to the protocol specification, in the forwarding system of the 4G network, the direction from the BBU to the RRU is referred to as a downlink direction, and the direction from the RRU to the BBU is referred to as an uplink direction; in the forwarding system of the 5G network, a direction from the DU to the AAU is referred to as a downlink direction, and a direction from the AAU to the DU is referred to as an uplink direction.
In the present disclosure, a data frame format, i.e., the predetermined data frame format described in step S110, is defined. The predetermined data frame format is used for monitoring and controlling transmission and interaction of data between the near-end optical module and the far-end optical module. In step S110 of the present disclosure, when a far-end optical module needs to be monitored, framing is performed in the near-end optical module according to the predetermined frame format, and the monitoring instruction is generated. And the monitoring instruction generated according to the preset frame format can bear monitoring service information. The monitoring service is a service which is generated by the near-end optical module according to specific monitoring and control requirements and needs to be executed on the far-end optical module.
In step S120, the monitoring instruction is sent to the remote optical module by a downlink optical signal. The far-end optical module identifies and receives the monitoring instruction according to the preset data frame format, and further deframes the received monitoring instruction according to the preset data frame format to acquire and execute the monitoring task corresponding to the monitoring instruction, so that the far-end optical module is remotely monitored and controlled by the near-end optical module.
The remote monitoring method of the optical module defines a predetermined data frame format, is used for transmission and interaction of monitoring and control data between the near-end optical module and the far-end optical module, and the monitoring instruction generated according to the data frame format can bear the monitoring service which needs to be executed on the far-end optical module, so that the far-end optical module executes the corresponding service according to the monitoring requirement of the near-end optical module, and remote monitoring and control of the near-end optical module on the far-end optical module are realized.
The optical module is an optoelectronic device that performs photoelectric and electro-optical conversion, and has a limited service life. In general, the service life of an optical module is about 5 years. During use, the performance of the optical module may gradually deteriorate as the operation time increases, for example, as the operation time increases, the quantum efficiency of a laser emitting laser in the optical module may decrease, thereby causing the performance of the optical module to deteriorate. In addition, the optical module may also be affected by the environment to generate a fault, for example, the pollution and damage of the optical interface of the optical module may cause the loss of the optical link to be increased, thereby causing the optical link to be blocked; the optical module is also susceptible to ElectroStatic Discharge (ESD) damage due to dry environment or improper operation, which may cause performance change or failure of the optical module.
Through research of the inventor of the present disclosure, it is found that in the existing fronthaul system, an RRU or an AAU is pulled far through an optical fiber, and a remote monitoring means is absent for an optical module on the RRU side or an optical module on the AAU side. When the fronthaul system fails, it is necessary to determine whether an optical module on the RRU side or an optical module on the AAU side fails through manual maintenance. Therefore, the performance of the optical module at the RRU side or the AAU side cannot be pre-judged, the optical module cannot be replaced in time under the condition of performance degradation of the optical module, and a service fault of the fronthaul system caused by a fault of the optical module at the RRU side or the AAU side is actively avoided.
As an optional implementation manner, the remote monitoring method provided by the present disclosure may be used to monitor an operation state of a remote optical module. The monitoring of the running state of the remote optical module is the monitoring of the performance of the remote optical module.
Accordingly, as an optional implementation manner, the monitoring instruction in step S110 of the present disclosure includes a monitoring instruction, where the monitoring instruction is used to instruct the remote optical module to execute a monitoring service for monitoring the performance of the remote optical module.
In the present disclosure, the light module comprises a plurality of registers, i.e. performance monitoring registers, for storing performance quantity data of the light module, which can characterize a performance state of the light module. When the optical module has performance changes such as performance degradation or damage in the running process, the bottom layer software in the optical module can write the performance changes into the corresponding register in real time. The register is a small storage area for storing data in the optical module, and is a high-speed storage unit with a limited storage capacity. Each optical module comprises a plurality of registers, and corresponding data are stored according to different functions.
In view of this, if the performance energy data of the remote optical module can be obtained, the operating state of the remote optical module can be determined according to the performance energy data. In order to achieve the above object, in the present disclosure, a monitoring instruction is configured as a reading instruction, and a register header address storing the performance energy data of the remote optical module is carried in the monitoring instruction, so that a reading service is executed on the remote optical module, and the performance energy data of the remote optical module is acquired. Accordingly, as an optional implementation manner, the predetermined data frame format described in step S110 of the present disclosure includes an instruction type field and an address field.
The instruction type field is used for identifying the type of the monitoring instruction, and the address field is used for identifying the first address of the performance monitoring register of the remote optical module.
As an optional implementation manner, a reading character representation reading instruction is defined, and when the far-end optical module recognizes the reading character, a corresponding reading service is executed.
Further, as shown in fig. 2, in step S110, specifically through step S111a to step S111b, the monitoring instruction is generated according to the predetermined data frame format:
in step S111a, configuring the instruction type field as a read character;
in step S111b, the address field is configured as the first address of the performance monitoring register of the remote optical module.
When the remote optical module receives the monitoring command generated according to steps S111a to S111b, a monitoring service for monitoring the performance of the remote optical module is executed, that is, the performance energy data of the remote optical module is read from the performance monitoring register of the remote optical module according to the head address of the performance monitoring register.
In this disclosure, after the far-end optical module reads the performance data, a response signal is generated according to the predetermined data frame format, and the performance data is sent to the near-end optical module. Accordingly, as an alternative embodiment, as shown in fig. 3, after step S120, the remote monitoring method provided by the present disclosure further includes:
receiving a response signal sent by the remote optical module in response to the monitoring instruction, and extracting performance quantity data of the remote optical module from the response signal according to the predetermined data frame format in step S111 c;
in step S111d, the operating status of the remote optical module is determined according to the performance data.
The remote monitoring method provided by the present disclosure can also be used for controlling a remote optical module to execute a specific function. For example, when a service failure occurs in the legacy system, whether the service failure is caused by the remote optical module is determined by controlling the remote optical module to execute a specific function (for example, controlling the remote optical module to perform service loopback).
Correspondingly, as an optional implementation manner, the monitoring instruction in step S110 in this disclosure includes a control instruction, and the monitoring service corresponding to the control instruction includes a monitoring service for controlling a target function of the remote optical module.
In the present disclosure, a plurality of registers storing control parameters, i.e., function control registers, are also included in the optical module. The optical module executes corresponding operations according to the control parameters stored in the register to realize corresponding functions, so that the control of the functions of the optical module is realized, namely the control parameters stored in the register of the optical module are controlled. If the control parameters stored in the register of the remote optical module can be remotely controlled, the remote control of the remote optical module can be realized.
In order to achieve the above object, in the present disclosure, the control instruction is configured as a write instruction, and a register header address storing a control parameter of a remote optical module is carried in the control instruction, so that a write service is executed on the remote optical module, and a corresponding target function is executed. Accordingly, as an optional implementation manner, the predetermined data frame format described in step S110 of the present disclosure includes an instruction type field, an address field, and a data field.
The instruction type field is used for identifying the type of the monitoring instruction, the address field is used for identifying the head address of a function control register of the remote optical module, and the data field carries the control parameter corresponding to the target function.
As an optional implementation manner, a write character is defined to characterize the write instruction, and when the far-end optical module recognizes the write character, a corresponding write service is executed.
Further, as shown in fig. 4, the control instruction is generated in step S110, specifically through step S112a to step S112c, according to the predetermined data frame format:
in step S112a, configuring the instruction type field as a write character;
in step S112b, configuring the address field as a first address of a function control register corresponding to the target function in the remote optical module;
in step S112c, the data field is configured as a control parameter for controlling the target function.
When the remote optical module receives the control command generated according to steps S112a to S112c, the monitoring service for controlling the target function of the remote optical module is executed, that is, the control parameter is written into the function control register of the remote optical module according to the head address of the function control register, so that the remote optical module executes the target function.
It is understood that the predetermined data frame format described in the present disclosure further includes:
the preamble is a group of numbers at the beginning of a data frame and is used for synchronizing an optical module serving as a receiving end and preparing to receive actual data;
a frame start identifier for identifying the actual data start in the data frame;
a length field for identifying the length of actual data in the data frame;
the frame check code is used for checking the data in the data frame;
and a cut-off code for identifying the end of the data frame.
Fig. 5 illustrates an alternative embodiment of the predetermined data frame format. In fig. 5, PRE represents the preamble, Start represents the frame Start, Address represents the Address field, Write/Read represents the instruction type field, Length represents the Length field, Data represents the Data field, Check Sum represents the frame Check code, and End represents the End code.
The specific implementation manner of sending the monitoring instruction to the remote optical module through the downlink optical signal in step S120 is not particularly limited in this disclosure. For example, the monitoring instruction may be loaded onto a downlink main signal of an optical module through subcarrier modulation, so as to generate the downlink optical signal; the downlink optical signal may also be generated by coupling an optical carrier signal carrying the monitoring instruction with a main signal of the near-end optical module through Wavelength Division Multiplexing (WDM).
As an optional implementation manner, the monitoring instruction is loaded to the downlink main signal of the near-end optical module through a set top technology, so as to generate the downlink optical signal. Fig. 17 is a schematic diagram of the main signal being set according to the auxiliary signal. In addition, in the optical module, the processing of information is completed in the electrical domain, and when a signal needs to be sent, the information is firstly loaded on an electrical signal through processing, and then the electrical signal is converted into an optical signal, and then the optical signal can be propagated on an optical fiber.
Accordingly, as shown in fig. 6, step S120 specifically includes:
